Authorities in the northern province of Quang Ninh and Hai Phong City are checking Lenovo computers in their offices for fear that they may be infected with the Chinese manufacturer’s spyware, local media reported Tuesday.

A Tuoi Tre report said, as a precautionary measure, local agencies have been ordered to gradually replacing desktops and desktops made by Lenovo.

The move came after the Ministry of Public Security warned that many Lenovo computers were pre-installed with software which could pose threats to the devices’ information security, said Dang Huy Hau, vice chairman of Quang Ninh Province.
